JAMES EASTEVICK, OF FYNING VJ'OOD, ENGLAND.

MAGAZINE FOR Sl-YEALL-ARMS.

Application filed June 15, 1915.

To all whom it may concern:

Be it known that 1, James EASTWICH, a subject 01"" the King of Great Britain, residing at *F'yning -Wood, in the-parish of Rogate, in the county of Sussex, England, have invented new and useful Improvements in Magazines for Smalldlrms, 01 which the following is a specification.

This invention relates to rotary magazines for automatic and other rifles which are worked by, and therefore necessarily synchronize with, the longitudinal motion of the bolt.

it is specially adapted for use with a weapon such as is described in my patent specification No. 1,109,910, of September 8, 191%.

In order that my invention may be more readily understood 1 will describe it with 0 reference to the accompanying drawings Figure 1 of which is a longitudinal section, Figs. 2, 3, 4c, 5 and 6 are cross sections on the lines AA, B-B, CC, 3-D and EE of Fig. 1, Fig. 7 is a plan, Fig. 8 a horizontal section on the line FF of Fig. 2, Fig. 9 an underside view, Figs. 10 to 15 show details. Fig. 16 is a central vertical longitudinal section of the weapon with the breech bolt in place, the magazine being unloadedf Fig. 11" an underside view of the bolt and weight removed from the weapon; and 18 is a similar view of a modification. Fig. if) is a part section showing a clip of cartridges in position for loading the magazine; and Fig. 20 is an enlarged detail. 1 is the magazine casing on the bottom of which are pivoted 2 two bars 3, 3 the front ends of which are kept apart by a spring -l. The front and rear ends of these bars normally rest above suitable bearings or shoulders a on the gun. By pressing together with the fin ers two knobs a which project downward om the frontportions of t is bars, the ends of the bars are removed from above the bearings (r. so that the magazine can drop out of the gun.

1n the front and rear walls of the casing is journaled a spindle 5 to which is keyed a drum 6 adapted to receive five cartridges 7), the drnm is fitted with transverse diaphragms 7, 7 which keep the cartridges in their proper relative positions. The spindle ies toward its rear extremity two ratchet wheels 8, 9 which are turned step by step each time the bolt is actuated. As shown in Figs. 5, 10 and 11 the teeth of Specification of Letters Eatent.

the wheels are engaged by two bell crank levers 10, 11 pivoted to the rear wall of the casing and turned on their pivots by two transverse bars 12, 13 adapted to be "trans versely reciprocated by the longitudinal movements of the bolt (Z or the gear connected with it in a manner similar to that described below. After the bolt has been withdrawn clear of the magazine opening 6 in the frame f the last part of the rearward movement thereof causes the bell crank 10 to engage a tooth on the wheel 8 and to turn the spindle 5 through 1, small angle. The first part of the return movement of the bolt causes the bell crank 11 to engage a tooth on the wheel 9 and thus to turn the spindle and with it the drum sul'liciently to raise a cartridge into a position in which it will be caught by the bolt and thrust forward.

In Figs. 12, 13, 15, 16, 17, 19 and 20 I iave shown modified mechanism by which the same movements of the spindle can be accomplished. Here the movements of the wheels are effected by teeth 11, 15 on abar or plate 16 which can be slid transversely on guide pins 17 by a cross bar 18 actuated by inclines (Z on the weight h. The spindle 5 though it rotates with the drum is capable of an independent longitudinal motion. In ordinary working the two are kept in the same relative position by a spring 19. At the rear of the spindle is a vertical cross bar 20 having at its upper end an inclined plane 21 and at its lower end a surface 201 against which the cut-oil hereinafter described impinges. fired the next initial movement of the drum causes a stud 23 carried by an arm 22 on the drum to bear against a part 2 t of the frame, which )rcvents further rotation of the cartridge drum. At this time the tooth 15 of the plate 16 is in engagement with the double tooth 91 of the ratchet 9 as hereinafter described. blince the plate 16 is rigidly carried by the sliding bar 18, transverse movement of the bar 18 is prevented and the ends thereof being in engagement with the inclines (Z on the weight 73-, the bolt is held in its backward position. Then, when a clip with new cartridges is placed in position, it impinges against the inclined plane 21 and presses back the cross bar 20 and with it the spindle sutliciently to free the ratchet wheels from the bell cranks 10, 11 or the teeth 14, 15 of the plate 16, as shown in Fig.

When the last cartridge has been 19, compressing the spring 19 at the same time. The cartridges can now be pressed into the magazine, the drum and splndle rotating backward to admit them, the clip.

meanwhile keeping back the bolt. When the magazine is refilled, the spring 19 brings the ratchet wheels into gear again as the clip is removed and the action proceeds as before. 7

When the magazine is full the cartridges are in the position shown in Fig. 2, the ratchet wheels being in that shown in Figs.

10 and 13. lVhen the clip is removed the until the last cartridge is raised. Then the next backward movement of the bolt pro- .duces, owing to the spacing of the teeth, av

rotation of 10 only and at the commencement of the forward movement the tooth catches on the notched or double tooth '91 of ratchet wheel 9 and the whole is locked with the bolt in its back position.

The cut-off is an eccentric placed below the base of themagazine (see Fig. 9). When rotated into the proper position it presses back the cross bar 20. This frees the ratchet wheels from the bell cranks as before described and so leaves the bolt free to'work the transverse bars 12, 13 without affecting the magazine. But the cut-off presses back the spindle farther than the clip does and this furth r pressure causes notches or teeth 26 on the spindle to engage corresponding studs or teeth 27 on the casing of the magazine and so prevents all rotation (see Fig. 6). On the cut-off being rotated back the spring 19 brings the ratchet wheels into gear once more. Figs. 19 and 20 show clearly the intermediate position of the-wheels 8 and 9 into which they have been pushed back by the clip so far that they are out of engagementwith the teeth 1 1, 15 but not so far that the teeth 26 en gage the fixed teeth 27.

I place in the chamber 9 of the rifle a plunger 28 which presses against a bell crank 29 pivoted to the gun and this bell crank in its turn presses against a lever 30 which is pivoted to the magazine casing and in its turn presses against the head of the "spindle 5. When a cartridge is in place the plunger 28 is pressed down and the spindle is pressed back to the same extent as by the cut-off; the result is that the magazine can only work when the chamber is empty and thus all risk of double loading is avoided. When the cartridge is extracted the spring 19 in bringing back the ratchet wheels into gear presses up the piston again.

31 is a lever working with the bell crank 29 and gearing into an index bar 32 fitted in the receiver so that the index bar rises or falls as the piston falls or rises and thus indicates at once in ordinary working whether the weapon is loaded or not. These parts are shown separately in Fig. 1%. in

hand loading, when the cut-elf is in use and ber on the wheel corresponding with the number of'cartridges in the magazine appears in the proper position opposite an orifice 35 in the base plate so as to indicate the number of' cartridges in the magazine,

whether the breech be'open or not.

When any danger to the ammunition in the magazine from the shock offiring or the motion of the piece is apprehended, the

diaphragms 7 7 on the drum are arranged so that together with corresponding ribs 36 on the casing they grasp the case by its run and shoulder and also the bullet near itsnose and so keep case and bullet secured in their relative positions.

of the spindle is a wheel If two or more forms of bullet are used the grasp on the bullet must be arranged at some common point; the best way of doing this .(in cases where such a course is admissible) is to provide a shallow cannelure 37 on the bullet in which a rib and diaphragm engage. The of- 7 feet of the ribs and diaphragms is continued by corresponding ribs or pro ect1ons 38 in the opening in the frame f through which the cartridges rise so that the uppermost cart-ridge is secured as well as those in complete contact with the drum; design shown the uppermost cartridge cannot fall out during march with the breech open, but in cases where there is any such In the i risk a catch 39 is .fOll'leCl on the transverse bar 12 or 16 which, when the bolt is fully drawn back and the bar hard over, holds the rim of the cartridge and on the commencement of the return movement frees it before theratchet wheels, spindle and drum begin to work.

Dispersing is provided for by forming the spindle in two pieces screwing into each other as shown at 4 0 in Fig. 1. ing the magazine from the stock and unscrewing the spindle. the drum, bar and spring fall out of their places.

On reniov Having thus described all the parts concerned in the present invention I will describe sufficiently to enable any person skilled in the art to understand the operation of such parts, a weapon as in Patent No. 1,109,910 and having my invention applied to it, as shown in Fig. 16.

The barrel A is screwed into the chamber 9 forming part of or rigidly attached to the frame 7 and at its fore end, which is not shown, it is secured to the stock in any convenient way permitting the barrel to move through a small distance relatively to the stock.

C is a bolt carrier inclosed within the weight 7), and which carries the bolt (Z having on its front end locking lugs 1) adapted to enter grooves E in the chamber so that the bolt can be locked thereby.

F is a firing pin passing axially through the bolt. Surrounding the firing pin is a firing spring G and also an unlocking spring H, these two springs being kept apart, so that they may not rub one upon the other, by a sleeve I extending rearward from the bolt carrier. When the piece is fired the weight lurches forward relative to the rest of the mechanism, or more strictly remains stationary, owing to its inertia, and does not partake in the first portion of the recoil, and thereby compresses the springs G and H. The firing pin is thereupon locked to the weight so that the spring G cannot expand until the trigger is again pulled to fire, but the spring H immediately expands and therefore the weight is thrown backward again carrying with it the firing pin. This rearward motion of the firing pin turns, through the lands and rifled grooves, the bolt in its bolt carrier and so forces the lugs D and the bolt is therefore free to move rearward out of the receiver, and the weight, bolt carrier, etc., more rearward along the raceway of the frame f.

The last part of the rearward motion of the bolt causes the inclines (Z (seen in Figs. 17 and 18) to actuate the bell crank 10 or the plate 16 as already described to rotate the magazine through a small angle and the first part of the return movement (due to parts not shown but well understood) causes the bell crank 11 or the plate 16 to turn the magazine sufficiently to raise a cartridge into a position in which it will be caught by the bolt and thrust forward. Moreover at the commencement of recoil and during the lurch of the weight, the barrel, frame 7 and magazine have recoiled relatively to the stock and in so doing have compressed a recoil spring J arranged between the rear block K and the casing of the magazine. This spring is of such a strength that it expands again during the backward travel of the weight so that the frame f is urged forward relatively to the stock by the spring while the weight is traveling rearward relatively to the stock by the spring H coupled with the effect of recoil, the result of these movements being an increase of power in the Weight.

The casing of the magazine is rigidly attached to the frame f so as to slide with it.

The trigger gear is attached to the frame 7 and is connected with the trigger L by a bar M.

A retaining clutch N is attached to the raceway by a pivot 0 so that when the weight and the frame 7 are in their forward positions the weight is secured to the frame but on the recoil before the backward motion of the weight begins the clutch is removed and then cannot return to its place until the weight and frame 7 are again in their forward positions. This clutch is so arranged as also to secure the raceway to the casing and is operated by the trigger.

The trigger L presses by means of a bell crank P against the arm Q of the retaining clutch N. In the uncooked position in addition to the bolt being locked home,.the weight it is held by a tooth R of the retaining clutch and the end S of the clutch rests against the rear block K. The weight is thus secured to the raceway and the raceway to the stock. On pulling the trigger the arm Q is pressed back, the tooth R is low ered but not sufficiently to release the weight altogether and the end S of the clutch is raised so that the sloping surface U is placed against a corresponding slope V on the rear block K. At the same time the bar M is drawn back, the trigger spring V is partly compressed, a bell crank X pivoted to the magazine casing is moved and a plunger Y is thereby lifted until it comes nearly against the front end of the clutch N. The upper end of the plunger now presses up the forward end of the sear Z, thus throwing the sear out of the bent Z, on the firing pin F and the piece fires. It is this sear which catches the bent when the weight lurches forward and locks the firing pin to the weight so keeping the spring G compressed as referred to above. On the commencement of recoil the incline U is forced against the slope V, the spring is further compressed, a spring flap a: on the bell crank X is freed from the plunger Y, the tooth R is lowered out of the way of the rearward travel of the weight and the front end of the clutch N presses down the plunger Y into its original position. A tooth 2 on the sear when the latter is out of bent enters a recess 2 in the frame 7 so that at the end of the forward lurch the tooth is forced backward and the sear raised into bent. The whole mechanism is now free to move until both the raceway and the weight it return to the positions shown. Then the spring W 'rotates the clutch N on its pivot into the position shown and at the same ,time moves back the bell crank X, the flap 50 opening and so slipping past the shoulder y on the plunger and the piece is ready to fire again.
